NR 509 WEEK 3 QUIZLET CURRENTLY TESTING
WITH DETAILED QUESTIONS AND CORRECT
ANSWERS GRADED A+| CHAMBERLAIN
UNIVERSITY
1. A nurse is performing a physical assessment on an adult
patient's upper extremities. When asking the patient to move
his arm inward toward the midline of his body, the nurse is
assessing which range-of-motion movement?
A. Flexion
B. Abduction
C. Adduction
D. Extension
Answer: C
Rationale: Adduction refers to the movement of a limb toward the
center or midline of the body. Abduction is movement away from
the midline, while flexion decreases the angle between bones.
, 2. A patient reports difficulty feeding herself and brushing her
teeth due to an inability to bend her elbow and bring her
hand toward her mouth. Which movement is impaired?
A. Flexion
B. Abduction
C. Adduction
D. Extension
Answer: A
Rationale: Flexion is a bending movement that decreases the
angle between two body parts, such as bending the elbow to
bring the hand to the mouth. Extension would straighten the joint.
3. During a lecture on musculoskeletal anatomy, an instructor
asks which structures represent the functional units of the
musculoskeletal system because they enable mobility. Which
structure should the students identify?
A. Joints
B. Bones
,C. Muscles
D. Tendons
Answer: A
Rationale: Joints (articulations) are the functional units of the
musculoskeletal system because they permit the mobility required
for activities of daily living. Bones provide the structural
framework, and muscles provide the force.
4. When reviewing a patient's lab work showing altered blood
cell counts, the nurse considers the physiological role of the
skeletal system. In which skeletal component does
hematopoiesis take place?
A. Liver
B. Spleen
C. Kidneys
D. Bone marrow
, Answer: D
Rationale: Hematopoiesis, the production of blood cells, occurs
within the red bone marrow of long and flat bones. The liver and
spleen can undergo extramedullary hematopoiesis under
pathological conditions, but bone marrow is the primary site.
5. A patient presents with a joint injury. The nurse explains that
fibrous bands connecting bone directly to bone provide
stability and prevent movement in undesirable directions.
What are these structures called?
A. Bursae
B. Tendons
C. Cartilages
D. Ligaments
Answer: D
Rationale: Ligaments are fibrous bands running directly from one
bone to another that reinforce joints and prevent abnormal or
excessive movements. Tendons attach muscle to bone.
